This part is very revealing

It's just not going to happen.
"The main obstacle to getting the tournament across the line remains the vexed issue of promotion/relegation.
Italy, Scotland and Ireland have been firmly against the concept of relegation because it doesn't secure their Six Nations involvement. And with the competition to run every second year, so as to not interfere with the World Cup and British and Lions tour, relegation would see a nation be on the outer for at least two years.
France and England are less adverse to the concept, but even the Rugby Football Union said it would be "catastrophic" if they were relegated.
"For us it could be catastrophic being relegated, commercially," RFU acting chief executive Nigel Melville said in March.
"To be relegated, the catastrophe isn't just the team being relegated, it's our ability to fund the game as a governing body in England.
"Can we fund the community game in England to the level we do now if we don't have the revenues we have? And on the point of promotion and relegation, there's no promotion and relegation in a Lions year and there's no tournament in a World Cup year.
"So when you're relegated, you're relegated for two years, not one. It's not quite up and down, one season on the naughty step and go back up, it's actually two years and that could be a disaster for people."
